DIY Cheap Arduino CNC Machine

This video shows how to set up an Arduino, Stepper motors, and a GRBL Shield to create an inexpensive but powerful DIY CNC system!

The GRBL Shield is a great way to use G-Code to create an Arduino-based CNC machine, but setting up the software and wiring the hardware can be confusing! This video walks through every step of the process!

This video is a “foundation” video for two CNC machines we are about to do a DIY build-series of videos one: one is a DIY CNC gantry sorting machine, the other is a DIY CNC Pneumatic Engraving machine!

In Part 1, we set up the Arduino & GRBL shield. Now, let’s use inexpensive linear motion hardware to assemble the bearings, rods and steppers into a functional CNC machine!

In this video, we added a Z-axis spring and bushing that lets us use the project as a pen plotter with a pen “lift” and a pressure spring that will accommodate any variations in paper thickness, unevenness, etc! We also look at the *awesome* ChiliPeppr interface which is a incredible – a huge step above the Universal G-Code Sender we used in Parts 1 and 2!
